PaaS 平台多租户索引优化机制
首发时间:2019-10-08
摘要:随着云计算技术的发展,持续交付技术逐渐成熟,PaaS平台提供了一种更加适合业务扩展,功能不断迭代的软件开发架构。本论文从多租户数据隔离和安全出发,详细设计了信息安全综合PaaS平台,构建了符合业务需求的多租户数据库实例化模型,通过宽表、透视表实现租户数据的隔离与共享,采用元数据驱动的方式实现租户定制化,对比传统的多租户数据库索引方法,本文提出多租户索引优化机制,并采用多种手段优化多租户数据库,实践表明,多租户索引算法有效提高检索速度,数据库性能有效提升,从而能够更好地满足云环境下具有多租户共享、可动态定制云资源的需求。

PaaS platform multi-tenant index optimization mechanism
Abstract:With the development of cloud computing technology and the continuous delivery technology, the PaaS platform provides a software development architecture that is more suitable for business expansion and function iteration. Based on the isolation and security of multi-tenant data, this paper designs the information security integrated PaaS platform, builds a multi-tenant database instantiation model that meets the business requirements, and realizes the isolation and sharing of tenant data through wide tables and pivot tables. Metadata-driven approach are usedfor tenant customization, Compared with the traditional multi-tenant database indexing method, this paper proposes a multi-tenant index optimization mechanism and uses multiple methods to optimize the multi-tenant database. Practice shows that the multi-tenant indexing algorithm effectively improves the retrieval speed and effectively improves the database performance, so that it can better meet the requirements. The need for multi-tenant sharing and dynamic customization of cloud resources in a cloud environment.
